We evaluate the performance of our approach using the two-dimensional HP model [1]} as a testbed. In particular, we consider
a set of sequences with up to 30 beads, for which the exact solutions are known from exhaustive enumerations of all
structures [2]}, [3]}. In addition, we present results obtained for two longer sequences [4]} with 48
and 64 beads, respectively, which have been studied by various classical methods.
